DAP-ROVEMENT IN CORN-PLANTERS.

The Schedule referred to in these Letters Patent and making part of the same.

.To all whom it may concern: f- Be it known that I, C. W. T111Essn1v,of Eiiingham, in the county of Eingham, an'dState of Illinois, have invented anew and improved Corn-Planter; and I do hereby; declare that 'the following isaifull, clear, and exactr' description thereof, which `will enable others skilledin the art to make and use the same, reierence being had to the accompanying drawings, forming a partkof this specification.

Figure l represents a vertical section of my improved planting-wheel, the plane of section being indicated by the `line :v x, iig. 2.

Figure 2 is a vertical cross-section of the wheel, taken on the plane of the line y y, fig. l.

Figure 3 is a front elevation of my improved cornplanter.

4Similar letters of reference 'indicate corresponding rparts.

lThis invention relates to a new corn-planter, which is so arranged thatthe wheels contain the seed-box and the dropping-apparatus, whereby a very secure and.

regular distribution of the seed is obtained.

' The invention consists in such an arrangement of adjustable slides, that work on the face of the wheel, in boxes projecting from the face of the wheel, and in such a combination of the saine with a seed-box, secured to the inner side ofthe wheel, that the requisite quantityof seed is dropped during each full, half, or otherpartial revolution of each wheel, and that such seed is, by such revolution of -the wheel, not only dropped, but also securely embedded in the soil.

A, in the drawing, represents the axle of my improved seed-planter. i

B B are the .two wheels, hung loose on thc ends of the axle.

C is the dlivers seat, fixed to the axle.

I) is the shaft or pole, projecting from the axle.

Each wheelB is a metal or other disk, fitted loosely varound the end of the axle.

' To the inner face of each wheel is secured a sheetmetal or other box, or pan',yE, which forms a seedreceptacle, or, if it is, as in the drawings, divided by means of partitiolpisvlv a, into a series of compartments, a series of seed-receptacles.

Each seed-1eceptacle is provided With'a door, l), for

Iallowing the .insertion of the seed.

corresponding to the number of seed-receptacles in the i pan E. Each drop-box communicates with its opposite seed-receptacle by a peribration through the plate, B,which pertoration is shown at h, in fig. 2. This perforation connects with a recess, yi, in. one of the ribs, as in lig. l. Each drop-box has or is part of a projecting tooth, c.

Each slide g is, by means ofa connecting-lod, j, se-

cured to the end ofthe axle A, the pivot-pin L', by which the rods are lpivoted to the' axle, being secured to the axle below the centre of the axis of the wheel.

Thereby the slide will be pushed out to the end of itsl tooth, c, when it stands vertically below the axle, while it will be drawn down when it is vertically above the axle, as in iig. l.

Into that edge of each slide g which works along the recess Ii, is out anotch, I, and a similar notch, m, is cut into the same rib in which the recess i is arranged.

The spring j' constantly closes the outer end of each drop-box, unless the slide is pushed quite out, when it yields to the slide, as can be understood from fig. 2.

The operation is as follows:

When the apparatus is drawn forward, the wheel revolves in the direction of the arrow in fig. l.

Supposing the slide and drop-box to be in a horizon tal position in front ofthe axle A, then the notch Z in the' slide is under the recess fi, and is lled with seed from .the seed-receptacle. The wheel revolving, the slide is gradually pushed outward until it is vertically below the axle. Then the seed, held in the notch Z, is separated from the contents of the box E, and is, as the notches l and m come in line, deposited in the notch m.

As the wheel continues to revolve, the slide is chawr in again, leaving the seed in the notch m undisturbed, until the slide and drop-box are vertically above the axlf` A. Then the slide is (ha'wn down, as shown, and the seed drops out of the notch m upon the end of the slide, as indicated in iig. l.

The seed now remains in the outer end of the drop box. When the latter arrives again 'in front of the axle, the recess lis again filled, and then there are twolots of seed confined in the drop-box. The one that is in the outer end of the drop-box is pushed out into the ground by the slide, when the same is vertically below the axle. once 1nore,`so as to be discharged in the same manner.

Thus each drop-box deposits one lot of seed during each revolution of the wheel, and if there are two or more such (hop-boxes arranged on one wheel, there will be an equal number-of hills planted during -each revolution.

The seed cannot be blown away, after having been planted, as it is deposited at some length below the ground by the projecting portion c of the drop-box.

When the dropping-apparatus is to be thrown out of gear, the pin K is taken out of the axle, and is fastened in a hole, fn, provided in the plate B. Then the slides will not be operated, and seed will not be dropped.

The other is carried all around It is evident that the planting-apparatus may be zirrrmged, on bot-l1 or either one of the wheels of one @ornplzinter.

Having thus described my invent-ion,

YNVllzi' I claim as new, md desire to secure by Letters Patent, is

,1. The drop-box, constructed as described, of the parallel ribs l d, one of which is provided Within the seed-receptacles 'i my, as herein set forth l 1d shown.

2. The circ-ulm' seed-receptacle E, constructed as de scribed, and secured to J511e inner ffice of the wheel B, within the mige c, as herein set forth and shown.

3. Pivoting the conueeting-rodsj of the slides I/ by men-ns of u common pin7 K, to the Stationery axle of' the revolving wheel7 so that, by the revolution of the wheel, t-lle slides will receive reciprm':11inelr motion in the drop-boxes, snbstzultizdly as set forth.

4. The arrangement of' the circular semi-receptacle E md slides 1/ upon opposite sides of the wheel l, :is herein described, for the purpose specified.
